Window construction customarily (involves a more or less cumbersome sash framing to carry the glass, and the sashes are movable in .the frame by use of counterweights or the like. In the present invention the complication of the sash framing is eliminated, and also the counterweights. correspondingly, a construction may '.be had which is particularly simple and eifective, and also advantageousin cost. Other objects and advantages of the invention will appear from the following description.

To the accomplishment of the foregoing and related ends, the invention, then, comprises the features hereinafter fully described and particularly pointed out in the claims, the following description and the annexed drawing setting forth "in detail certain illustrative "embodiments of the invention, these being indicative, however, of but a few of the various ways .in which the principle of the invention may be employed.

In said annexed drawing:

Fig. 1 is an elevational view .of a window in accordance with the present invention;

Figs. 2 and 3 are enlarged sectional views taken on planes respectively indicated by lines II-II and III-IIL'Fig. 1, central portions being broken out on account of space limitations;

Fig. 4 is a fragmentary front elevational detail of the closing means; and

Fig.5 is a fragmentary detail of the support.

In generaL'the construction provides amounting in which the glass panes are directly slidable in a support means without intervention of conventional sash framing. As seen from the inside view at Fig. 1, the Window as a whole may be set within the usual window trim 'I, and involve a carrier frame F, Fig. 3, which is inserted in the window frame opening W in the wall, and which may be of sheet metal with channel fianging 2 at one face, preferably the outer, to include a sealing gasket 3 of rubber or the like. By reason of such carrier construction, considerable latitude of warpage in the window frame opening, as notably found in old houses, may be accommodated for, and the pane support means freely centered in the opening. The support means S may be hinged to one side of the carrier frame, as for instance by a piano-type hinge 4, and at the other side may be provided with one or more catches to hold it in closed position in the carrier frame. Such catch means, for instance, may be in the form of a member pivoted at 5 to the support S and having one arm 6 as a thumb latch for manipulation, and its other arm I ending in a slightly resilient extension 8 to look over the edge of-an-operiing 9 in the carrier frame F. With this, the entire glass mount support may be unla'tched and be swung inwardly, for example, to permit cleaning of the glass in convenient manner, and by the catch means may be held in closed position at other times. i

Desirably, the glass support means may be et outer and inner "opposed sheet mean channels H], 11, these being suitably interlocked together. The glass panes U, L, are slidably adjustable for openingto such extent 'as-des'ired. Each'pane is "held in its adjusted position byfricticnal en-- gagement of its margin *in the support means. Thus, the inner channel H is provided with grooves or longitudinal recesses 12, and to increase the resilient grip on the panes, the floor portion 13 of the grooves is enlarged arcua'tely, whereby the groove 'wallexerts resilient pressure upon the margin of the pane. Each pane may thus be slidably adjusted to any desired position ofopening or closing, and will remain at such adjusted position. with their attendant space requirements are thus eliminated, and the construction correspondingly is simplified and more compact, besides doing away with common difliculties of breaking of sash cords, jamming of weights, etc. By having small openings at the top anl bottom corners of the hollow-support to, H, asufficient circulation of air is provided -to obviate moisture condensation inside. I-he most usual arrangement of the panes involves upper and lower panes in vertical sliding arrangement, but the same principle applies in situations requiring horizontal sliding.

A narrow sheet metal binding l5 may be carried by the top and bottom edges of the glass, and this will provide for the handles 2| as well as protect the edges of the glass against chipping. The glass will ordinarily be thicker than single thickness grade, and where desired with thick glass the sheet metal binding may be omitted.

Since each glass pane retains the position in which it is put, and there is no weight thereof to be supported by special means, the sealing of the joint between adjacent edges of the panes is relatively simple. For this, a bar ll of rectangular section, and advantageously of a light metal, such as aluminum, is mounted by trunnions l9 at its ends in bearing holes in the inner channel II. The latter may be reinforced with a further thickness of sheet metal at such points if desired. The bar II has a narrow diam- Counterweights or the like eter and a wider diameter whereby when the wider diameter is parallel with the general plane of the glass panes, as shown in full lines in Fig. 2, the panes can be moved past the sealing bar to any desired position. Small handles 2|, for instance, on the binding may facilitate such moving of the glass pane. When, however, the panes are in closed position and the bar I! is turned down by its handles 23, as shown in dotted line position in Fig. 2, the bar closes against the respective edges or the panes, and

by having attached gasket strips 24 the weathertight seal is maintained. The handles 23 are pivoted, as shown in Fig. 4, at 20 in slots in bar I1, so as to swing laterally into slight recesses t in the adjacent edge of the channel II for locking in closed position. Where desired a small coil or other spring in the groove and bearing against the handle 23 may normally urge it to locking position.

In order to permit insertion and changing of the glass panes in the support S, one side of the latter, 25, Fig. 5, is removable. For instance, screws 26 may take through the support section 25 into a bracket 21 secured within the adjacent support section. A similar screw connection is provided at the lower end.

Advantageously, a packing strip of rubber or the like 16 may be provided to seal the lower edge of the lower pane.

The sheet metal may be of steel, but more advantageously a non-rusting metal, aluminum, bronze, or other, is applicable.

The operation of such construction is apparent from the foregoing. n releasing the handles 23 and rotating the closure bar ll into nonlocking position, the glass panes can be slid to positions as desired; and when the glass panes are in closed position and. the handles 23 are turned down to bring the bar I! into sealing position and are locked, the joint is weathertight. To clean the window, the entire support S can be swung inwardly, the catches 6 having been released, and then with the support returned to its closed position, the catches 6 may hold it in locked position.

Other modes of applying the principle of the invention may be employed, change being made as regards the detail described, provided the features stated in any of the following claims, or the equivalent of such, be employed.

I therefore particularly point out and distinctly claim as my invention:

1. In window construction, the combination of slidable panes, outer and inner opposed sheet metal channels secured together, and means resiliently holding said slidable panes in desired position including the web of said inner channel formed with a pair of longitudinal grooves, said web being in a completely flat plane transversely and thereby presenting groove-margins which grip the slidable panes in such fiat plane, the floor of the grooves being arcuately expanded as a substantially complete circle in section pressing said groove margins toward each other against the pane, and integral means in said sheet metal web extending from the respective outside margins of the grooves in the same fiat plane for lateral support.

2. In window construction, the combination of slidable panes, and means resiliently holding said slidable panes in desired position comprising a sheet metal framing element having a pair of longitudinal grooves and being in a completely flat plane transversely and thereby presenting groove-margins which grip the slidable panes in such fiat plane, the floor of the grooves being arcuately expanded as a substantially complete circle in section pressing said groove margins toward each other against the pane, and integral means in said sheet metal element extending from the respective outside margins of the grooves in the same flat plane for lateral support.-
